does anyone know where i can find a manual for this motherboard? i cant seem to find any info about it. i would like to know what is the fastest processor for it and if there are any bios updates for it.
Not sure about any manuals, but the board itself can tell us a lot:
- So5, so single-voltage and possibly only 1.5/2.0 multiplier
- i430FX with no visible L2 cache - that castrates an otherwise excellent chipset, this thing will crawl 🙁
- Supports EDO DRAM, max 128MB, with max 64MB cacheable - if you have any cache, that is...
Actually, I think it's a very lightly modified (PS/2 instead of DIN) Intel Advanced/ZP ('Zappa') board. In which case this is what switches & connectors do:

So yes, 2x66MHz = 133MHz is fastest supported CPU. You can fit a Pentium (non-MMX) 200 if you set BF1 pins manually (minor mod on CPU or back of motherboard behind socket).
But tbh, if yours also doesn't have any L2 cache, it's not really worth doing anything with this slug 🙁 - unless you fancy soldering on some SRAM, in which case you get a decent very early i430FX board.
As for BIOS updates: why do you think you need one?

thanks for the info. im not above modding the cpu to get something faster in it. or modding to motherboard. im pretty handy with the soldering iron. i was hoping a bios would be available that would allow a cpu upgrade do you have any information about how to mod a cpu as you suggested? this is not my main retro machine its just something im messing with at the moment. i have a kt7a-raid with a 1ghz athlon that i retro game on.

By far the biggest speed boost would be soldering on L2 cache. You might also need a few SMD filter caps and resistors. Try and find a high-res picture of the upper right-hand part of the board to see what you need.

You need to connect BF1 to GND/Vss for a 0, which will enable 2.5x and 3x multipliers (selected by the switch for BF0). Which GND you use doesn't matter, it can be one of the Vss pins on the CPU socket or anything else on the motherboard at GND.

thanks. i might give this a go.
